CASTRO VALLEY (CBS SF) — An 18-year-old Tracy woman is missing and feared dead after her car plunged into rain-swollen Alameda Creek in Niles Canyon Saturday and submerged in the fast-moving waters.

Officers responded at 10:45 a.m. to Niles Canyon Road, east of Palomares Road, where the woman was involved in a collision before she disappeared into the raging waters.

The woman, whose name is not being released yet, was in a silver 2000 Honda Accord traveling west when her car crossed over the double yellow lines in the road and collided with a white 2016 Honda Accord traveling east.

After the impact, the silver Accord veered to the right and into the creek.

The level of Alameda Creek is abnormally high now with fast flowing water because of the recent winter storms. That has made it unsafe for search and rescue divers to recover the car or the body.

But rescuers are working with state water resource agency officials to reduce the water level in the creek so rescue operations can begin.

Also slowing recovery was a landslide that has closed Niles Canyon to all traffic.
